inkling

Not new technology.

I've had gadgets that do the same thing for years.

Livescribe: http://www.livescribe.com/en-us/
Every thing you sketch is digitally captured. Uses a special paper with dots to do the digitizing. Drawbacks, uses ball point pen refills and the the ink is lousy for drawing. (Just like the Wacom Inkling.)No levels of sensitivity, either.

IOGEAR Digital Scribe: http://www.iogear.com/product/GPEN200N/
Uses a matchbox sized dock that you attach to the top of your sketchbook (Just like the Wacom Inkling.) Drawbacks, digitally captured lines are reproduced at a single width, default setting 1 pixel. Still has the same ball point refills as the Livescribe and the Wacom Inkling.

Both of these were bought for around $70 each. They were designed for taking notes and it shows. The Livescribe even has a built in microphone for recording the audio of your class/meeting as you take notes. The Livescribe is actually a potable computer while the IOGEAR Digital Scribe just digitally records your writing/drawing.  I carry both of them with me everyday.
